- Briefly disrupts sensory nerve impulse transmission from a specific body area or region.
- Because the gag and cough reflexes remain intact, the risk for aspiration is low.
- Often supplemented with sedatives, opioid analgesics, or hypnotics to reduce anxiety and increase comfort.
Local: is delivered topically and by local infiltration (injected directly into the tissue around an incision, wound, or lesion). Sometimes when the term local is used, it means any form of anesthesia that is not general anesthesia.
Regional: is a type of local anesthesia that blocks multiple peripheral nerves in a specific body region. It may be used when general anesthesia cannot be used because of medical problems, when the patient has had adverse reactions to general anesthesia, when the patient has a preference and a choice is possible. Types of regional anesthesia include field block, nerve block, spinal, and epidural.
Administered by infiltration of the surgical site with local anasthetics.
